Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain , , , , and .

Before using Redis with Laravel, we encourage you to install and use the phpredis PHP extension via PECL. The extension is more complex to install compared to "user-land" PHP packages but may yield better performance for applications that make heavy use of Redis. If you are using Laravel Sail, this extension is already installed in your application's Docker container.

If you are unable to install the phpredis extension, you may install the

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

3 package via Composer. Predis is a Redis client written entirely in PHP and does not require any additional extensions:

composer require predis/predis

Configuration

You may configure your application's Redis settings via the

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

4 configuration file. Within this file, you will see a

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

5 array containing the Redis servers utilized by your application:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),

Each Redis server defined in your configuration file is required to have a name, host, and a port unless you define a single URL to represent the Redis connection:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

Configuring The Connection Scheme

By default, Redis clients will use the

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

6 scheme when connecting to your Redis servers; however, you may use TLS / SSL encryption by specifying a

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

7 configuration option in your Redis server's configuration array:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),

Clusters

If your application is utilizing a cluster of Redis servers, you should define these clusters within a

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

8 key of your Redis configuration. This configuration key does not exist by default so you will need to create it within your application's

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

4 configuration file:

    'client' => env('REDIS_CLIENT', 'phpredis'),
                'host' => env('REDIS_HOST', 'localhost'),
                'password' => env('REDIS_PASSWORD'),
                'port' => env('REDIS_PORT', 6379),

By default, clusters will perform client-side sharding across your nodes, allowing you to pool nodes and create a large amount of available RAM. However, client-side sharding does not handle failover; therefore, it is primarily suited for transient cached data that is available from another primary data store.

If you would like to use native Redis clustering instead of client-side sharding, you may specify this by setting the

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),

0 configuration value to

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

5 within your application's

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

4 configuration file:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'cluster' => env('REDIS_CLUSTER', 'redis'),

Predis

If you would like your application to interact with Redis via the Predis package, you should ensure the

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),

phpredis Serialization & Compression

The phpredis extension may also be configured to use a variety of serialization and compression algorithms. These algorithms can be configured via the

    'client' => env('REDIS_CLIENT', 'predis'),

3 array of your Redis configuration:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),

Interacting With Redis

You may interact with Redis by calling various methods on the

    'client' => env('REDIS_CLIENT', 'phpredis'),
                'host' => env('REDIS_HOST', 'localhost'),
                'password' => env('REDIS_PASSWORD'),
                'port' => env('REDIS_PORT', 6379),

2 facade. The

    'client' => env('REDIS_CLIENT', 'phpredis'),
                'host' => env('REDIS_HOST', 'localhost'),
                'password' => env('REDIS_PASSWORD'),
                'port' => env('REDIS_PORT', 6379),

2 facade supports dynamic methods, meaning you may call any Redis command on the facade and the command will be passed directly to Redis. In this example, we will call the Redis

    'host' => env('REDIS_HOST', 'localhost'),
    'password' => env('REDIS_PASSWORD'),
    'port' => env('REDIS_PORT', 6379),
    'read_write_timeout' => 60,

5 command by calling the

    'host' => env('REDIS_HOST', 'localhost'),
    'password' => env('REDIS_PASSWORD'),
    'port' => env('REDIS_PORT', 6379),
    'read_write_timeout' => 60,

6 method on the

    'client' => env('REDIS_CLIENT', 'phpredis'),



 'host' => env('REDIS_HOST', 'localhost'),
 'password' => env('REDIS_PASSWORD'),
 'port' => env('REDIS_PORT', 6379),

As mentioned above, you may call any of Redis' commands on the

    'client' => env('REDIS_CLIENT', 'phpredis'),
                'host' => env('REDIS_HOST', 'localhost'),
                'password' => env('REDIS_PASSWORD'),
                'port' => env('REDIS_PORT', 6379),

2 facade. Laravel uses magic methods to pass the commands to the Redis server. If a Redis command expects arguments, you should pass those to the facade's corresponding method:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),

Alternatively, you may pass commands to the server using the

    'client' => env('REDIS_CLIENT', 'phpredis'),
                'host' => env('REDIS_HOST', 'localhost'),
                'password' => env('REDIS_PASSWORD'),
                'port' => env('REDIS_PORT', 6379),

Using Multiple Redis Connections

Your application's

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

4 configuration file allows you to define multiple Redis connections / servers. You may obtain a connection to a specific Redis connection using the

    'client' => env('REDIS_CLIENT', 'phpredis'),
                'host' => env('REDIS_HOST', 'localhost'),
                'password' => env('REDIS_PASSWORD'),
                'port' => env('REDIS_PORT', 6379),

2 facade's

8 commands. The

'aliases' => Facade::defaultAliases()->merge([
    'Redis' => Illuminate\Support\Facades\Redis::class,

6 method accepts a closure as its only argument. This closure will receive a Redis connection instance and may issue any commands it would like to this instance. All of the Redis commands issued within the closure will be executed in a single, atomic transaction:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),

Warning
When defining a Redis transaction, you may not retrieve any values from the Redis connection. Remember, your transaction is executed as a single, atomic operation and that operation is not executed until your entire closure has finished executing its commands.

Lua Scripts

The

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

0 method provides another method of executing multiple Redis commands in a single, atomic operation. However, the

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

0 method has the benefit of being able to interact with and inspect Redis key values during that operation. Redis scripts are written in the Lua programming language.

The

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

0 method can be a bit scary at first, but we'll explore a basic example to break the ice. The

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

0 method expects several arguments. First, you should pass the Lua script (as a string) to the method. Secondly, you should pass the number of keys (as an integer) that the script interacts with. Thirdly, you should pass the names of those keys. Finally, you may pass any other additional arguments that you need to access within your script.

In this example, we will increment a counter, inspect its new value, and increment a second counter if the first counter's value is greater than five. Finally, we will return the value of the first counter:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),

Warning
Please consult the Redis documentation for more information on Redis scripting.

Pipelining Commands

Sometimes you may need to execute dozens of Redis commands. Instead of making a network trip to your Redis server for each command, you may use the

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

4 method. The

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

4 method accepts one argument: a closure that receives a Redis instance. You may issue all of your commands to this Redis instance and they will all be sent to the Redis server at the same time to reduce network trips to the server. The commands will still be executed in the order they were issued:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),

Pub / Sub

Laravel provides a convenient interface to the Redis

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

6 and

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

7 commands. These Redis commands allow you to listen for messages on a given "channel". You may publish messages to the channel from another application, or even using another programming language, allowing easy communication between applications and processes.

First, let's setup a channel listener using the

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

7 method. We'll place this method call within an Artisan command since calling the

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

7 method begins a long-running process:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

0

Now we may publish messages to the channel using the

    'client' => env('REDIS_CLIENT', 'phpredis'),
    // Rest of Redis configuration...

6 method:

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'url' => 'tcp://127.0.0.1:6379?database=0',

Wildcard Subscriptions

Using the

    'client' => env('REDIS_CLIENT', 'phpredis'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),

01 method, you may subscribe to a wildcard channel, which may be useful for catching all messages on all channels. The channel name will be passed as the second argument to the provided closure:

Can we save an object in Redis?

Object Storing Procedure. In the Redis, Everything can be stored as only key-value pair format. Key must be unique and storing an object in a string format is not a good practice anyway. Objects are usually stored in a binary array format in the databases.

How to store data in Redis PHP?

php //Connecting to Redis server on localhost $redis = new Redis(); $redis->connect('127.0. 0.1', 6379); echo "Connection to server sucessfully"; //set the data in redis string $redis->set("tutorial-name", "Redis tutorial"); // Get the stored data and print it echo "Stored string in redis:: " .

How to serialize an object in PHP?

Serializing objects - objects in sessions ¶ serialize() returns a string containing a byte-stream representation of any value that can be stored in PHP. unserialize() can use this string to recreate the original variable values. Using serialize to save an object will save all variables in an object.

How do I store a list of objects in Redis?

Redis Lists It's possible to add elements to a Redis list by pushing items to the front and back of the list with LPUSH/RPUSH and can pop items from the front and back of the list with LPOP/RPOP. In the world of key-value stores, Redis is unique in that it supports a linked-list structure.
